The group has previously voiced opposition to an interim report by the Home Affairs Select Committee, which is leading the Prostitution Inquiry, over recommendations solicitation and sharing of premises by sex workers should be legalised.

NMN said the inquiry should now be disbanded and reformed with members obliged to declare any history of purchasing sex, as well as a mandatory 50 per cent of members being female.

The mass sexual abuse which took place in Rotherham between 1997 and 2013 is "deeply troubling", according to the head of an influential group of MPs.

Home Affairs select committee chairman, Keith Vaz, said MPs wanted to know how this abuse "was allowed to go unchallenged for so long":

The revelations from the Independent Inquiry into Child Sexual Exploitation in Rotherham are deeply troubling. The Committee will be questioning those in positions of authority at the time that these offences were being committed on how the sexual exploitation of children on a horrifying scale was allowed to go unchallenged for so long.

We will also be hearing from Peter Wanless and Richard Whittam QC about progress in their ongoing review of how the Home Office handled historical allegations of child abuse.

MPs have demanded answers from both South Yorkshire Police and the BBC as to how the broadcaster seemed to know about the raid on Sir Cliff Richard's Berkshire home before it happened.

Home Affairs Select Committee chair Keith Vaz has written to both sides asking them to explain themselves.

In the letter, Mr Vaz asks when the BBC first learned of South Yorkshire Police's intention to carry out the raid, how the BBC received this information and if the police force confirmed the time and date of the planned search to the BBC.

He also queries if it is possible that any BBC journalist behaved inappropriately during the handling of the case and asks for a response by Friday August 22.

Depending what the responses are, witnesses from the police and the BBC could be called to give evidence to the committee when they resume in September.
